At the Bell Museum of Natural History in Saint Paul, the lives of beavers across 2 million years are captured in two scenes. One is set in the Ice Age and showcases a giant beaver, an animal the size of a small black bear. The other is set in the early 1900s at Lake Itasca and captures the more familiar modern beaver chomping on wood and building a dam. Together, these scenes spark big questions: Why have beavers been important to Minnesota’s history since the Ice Age? How have they shaped the landscape and human activity? And how did we get from the giant beaver to the beaver we know today?

To explore these questions, Dr. Chantel Rodríguez draws on multiple ways of knowing. Fossils, archival records, ecological science, and Indigenous storytelling reveal a complex narrative of megafauna, community relationships, environmental change, and global trade. Through conversations with paleontologist Nicole Dzenowski, environmental historian Hayden Nelson, and traditional ecological knowledge expert Michael Waasegiizhig Price, this episode examines not just what happened, but how we come to understand it.
